- the linking rods 52 are pivotally mounted with the front arms 55 by a guide pin 522 extending through the front open space 513 and the intermediate holes 552 of the front arms 55 .
- the linking rods 52 are pivotally connected to the rear arms 54 by a guide pin 524 extending through the rear open space 512 of the seat 51 and upper holes 542 of the rear arms 54 .
- the positioning arm 53 is formed with two holes 531 at two ends thereof engaged with respective protuberances 518 of the seat 51 .
- the rear portion of the position arm 53 has a hole 532 through which the axle pin 533 extends through the rear open space 512 of the seat 51 , the torsion spring 57 and the intermediate hole 541 of the rear arm 54 .
- the rear portion of the position arm 53 further has a curved groove 534 for receiving the guide pin 524 extending through a rear hole 523 of the linking rod 52 .
- the curved groove 534 has a radial hole 535 extending therefrom.
- the positioning arms 53 are pivotally connected with the front arms 55 by an axle pin 537 extending through the front open space 513 of the seat 51 and upper holes 551 of the front arms 55 .
- the front arm 55 has an upper hole 551 , an intermediate hole 552 , and a lower hole 553 , wherein the upper hole 551 receives the axle pin 537 extending through a hole 536 of the positioning arm 53 while the intermediate hole 552 receives the guide pin 522 extending through the front hole 521 of he linking rod 52 .
- the torsion spring 57 is sleeved on the axle pin 533 and includes a coiled body at the intermediate portion and two legs 571 and 572 at two ends thereof
- One leg 571 of the torsion spring 57 bears against the guide pin 524 extending through the rear hole 523 of the linking rod 52 , the curved groove 534 of the positioning arm 53 and the upper notch 543 of the rear arm 54 , while the other leg 572 of the torsion spring 57 presses the inner bottom side of the rear open space 512 of the seat 51 .
- the control mechanism 60 comprises a locking bolt 61 , an axle 62 , a pawl 63 , a torsion spring 64 , a tension spring 65 an a pushbutton 66 .
- the bolt 61 extends through the radial slot 535 of the positioning arm 53 and engages with the upper notches 543 of the rear arms 54 .
- the intermediate portion of the bolt 61 is formed with an enlarged circular member 611 .
- the axle 62 extends through the pawl 63 and the torsion spring 64 and fitted into the recesses 519 on the top of the seat 51 .
- the pawl 63 has a pair of lugs each having a hole 631 for the passage of the axle 62 which extends through the holes 631 and the torsion spring 64 to keep the torsion spring between the two lugs of the pawl 63 .
- the torsion spring 64 has one leg 641 pressing against the top of the pawl 63 and another leg 642 fitted into a recess 510 of the seat 51 (see FIG. 7 ).
- the pushbutton 66 has a stop portion 661 at the intermediate portion thereof and a shaft on which are mounted a spring 65 and a packing ring 67 .
- the pushbutton 66 is arranged inside the end chamber 515 of the seat 51 , with its tip 662 pushing against the bottom of the pawl 63 (see FIG. 7 ).
- the sole 40 is formed at the top with a cavity 41 configured and sized to receive the roller assembly 50 .
- the cavity 41 has two openings 42 at the bottom and a hole 43 at the rear end of the front arms 55 are pivotally connected with the rollers 56 by a sleeve 561 , a bolt 562 and a nut 563 .
- the roller assembly 50 is fixedly mounted into the sole 40 by resin or the like, and the fixation may be accomplished by any other means well known to those skilled in the art and is not considered a part of the invention.
- the pushbutton 66 is first depressed to cause its tip 662 to push the pawl 63 to move upwardly, so that the pawl 63 will move the locking bolt 61 out of the notches 544 to the rear arms 54 .
- the torsion spring 57 will push the guide pin 524 to rotate the rear arms 54 and move the linking rod 52 which will in turn move the guide pin 522 to rotate the front arms 55 until the locking bolt 61 is engaged with the upper notches of the rear arms 54 , thereby driving the rollers 56 out the sole 40 to convert the shoe into a roller skate.
- the pushbutton 66 is turned so that the stop portion 661 of the pushbutton 66 is located at the lower position to lock the roller assembly 50 in place.
- the pushbutton 66 When desired to collapse the rollers 56 (see FIGS. 12 through 14 ), the pushbutton 66 is first turned so that the stop portion 661 of the pushbutton 66 is rotated to the upper position to align with the chamber 515 of the seat 51 and then the pushbutton 66 is depressed to make the tip 662 push against the pawl 63 to move upwardly thereby pushing the locking bolt 61 upwardly out of the notches 543 of the rear arms 54 , so that the front and rear arms 55 and 54 can be turned to collapse the rollers 56 until the locking bolt 61 is engaged with the lower notches 544 of the rear arms 54 thereby converting the roller skate into a sports shoe. Finally, the pushbutton 66 is turned so that the stop portion 661 is located at the lower position thereby locking the roller assembly 50 within the sole 40 .
